Check if you have bodyParser installed.

Express-validator recommends that it is called immediately after bodyParser in app.js.

Example:

 // bodyParser
 app.use(bodyParser.json());
 app.use(bodyParser.urlencoded({ extended: true }));

 // Express-validator
 app.use(expressValidator({
   errorFormatter: function(param, msg, value) {
       var   namespace = param.split('.'),
             root      = namespace.shift(),
             formParam = root;

     while(namespace.length) {
       formParam += '[' + namespace.shift() + ']';
     }
     return {
       param : formParam,
       msg   : msg,
       value : value
     };
   }
 }));

Unfortunately this is not much code to work with. But you could try it with:

app.use(expressValidator());

instead of 

app.use(expressValidator);
